From: Paul Bolle Subject: [PATCH] cpufreq: speedstep: remove unused speedstep_get_state Date: Mon, 06 Jan 2014 21:30:12 +0100 Message-ID: <1389040212.2562.3.camel@x41> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-pm-owner@vger.kernel.org List-ID: Content-Type: text/plain; charset="us-ascii" To: "Rafael J. Wysocki" , Viresh Kumar Cc: cpufreq@vger.kernel.org, linux-pm@vger.kernel.org, linux-kernel@vger.kernel.org The only caller of speedstep_get_state() was removed in commit d4019f0a92ab ("cpufreq: move freq change notifications to cpufreq core"). So building speedstep-smi.o now triggers a GCC warning: drivers/cpufreq/speedstep-smi.c:148:12: warning: 'speedstep_get_state' defined but not used [-Wunused-function] Remove this unused function.
